Macros defining bmRequestType field of USB device request,
given in table 9.2 USB 2.0 spec, are rather generic macros
which can be further used by other Host controller stacks.
So moving them to usb_defs header.

Move the struct ehci_ctrl defition from ehci-hcd.c into ehci.h
so it can be re-used by drivers. In particular, the mv_udc driver
can benefit from this move.

The interrupt endpoint handling code stores the buffer pointer in the QH
padding field. We need to make it the size of a pointer to avoid strict
aliasing issue with the compiler.

Interrupt transfers aren't meant to be used from the async list
(the EHCI spec indicates trouble with low/full-speed intr on async).
Build a periodic list instead, and provide an API to make use of it.
Then, use that API from the existing interrupt transfer API.
This provides support for USB keyboards using EHCI.
Use timeouts to ensure we cannot get stuck in the keyboard scanning
if something wrong happens (USB device unplugged or fatal I/O error)

Kill off ehci-core.h
It was used to specify some static controller data. To support more than
one controller being active at any time we have to carry the controller
data ourselfes. Change the ehci interface accordingly.
NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed
to do the same thing as other platforms. But the change for now is at least
compile clean.

Remove __attribute__ ((packed)) to prevent byte access to soc
registers in some gcc versions.
Having patches to enable ehci for the BeagleBoard lying around for
several months, this one was the show-stopper.
Switched to align(4), rather than remove the attribute, per suggestion
from Alexander.
Credits have to go to Laine Walker-Avina <lwalkera@ieee.org> for
finding the problem.

Commit 3ed1607 "USB: sync Queue Element Transfer Descriptor against
EHCI spec" added an "__attribute__ ((aligned (32)))" to the
declaration of struct qTD, as used for example in the Linux kernel as
well.
However, it turns out that this attribute causes errors in "usb start"
(like "ERROR: NOT USB_CONFIG_DESC 7b" and similar). Drop the attribute
again.

Appendix B "EHCI 64-Bit Data Structures" of the "Enhanced Host
Controller Interface Specification for Universal Serial Bus" (Rev.
1.0, March 12, 2002) defines additional fields which were missing in
U-Boot's struct qTD; as these are also present in recent versions of
struct ehci_qtd in the Linux kernel, we add them here, too.
This fixes some nasty memory corruption problems.

This patch adds routines to handle (flush/invalidate) the dcache for the
QH and qTD structures and data buffers. This is needed on platforms using
this EHCI support with dcache enabled (like the MIPS VCT board port).

IXP465 board and I find some errors in the code. This
patch fix:
- descriptor initizialization (config, interface and endpoint
must be one next-to the other when the USB_DT_CONFIG message
is send.
- FIX little/endian bigendian (introduce the CONFIG_EHCI_DESC_BIG_ENDIAN
and the CONFIG_EHCI_MMIO_BIG_ENDIAN)
- Introduce the linux version of the usb_config_descriptor and
usb_interface descriptor. This descriptor does't contains
u-boot extension.
